2040 Market St. Philadelphia PA
Five story concrete waffle-slab
120,000SF Office space
…several developers rejected property as not profitable
Redeveloped by PMC Property Group:
+ 8 floor overbuild
+ additional tower
= 308,000SF mixed-use
“semi-offsite” hybrid
Strategy
• Existing building = limited site access
• Lighter overbuild = more floors
• Uniform appearance across rehab, overbuild & new portions (interior & exterior)
• Prefab structural panel system for gravity & shear
• Composite joist system for floors
• Transfer via in-wall HSS prefab truss
• Prefab HSS “spandrel truss” below windows carries glazing, matches depth of original concrete floor
• 256 tons of steel for the addition
Shear Panel View
• Panels, transfer trusses & spandrels shipped from IL to PA
• Owner chose to have finishes & glazing installed locally (ensured match with rehab of existing building & used same sub)
